 |
|
ive got the howto from kerneltrap, but is there anything special that i need to do for initrd and grub, or anything else i should look out for?
Which packages should be updated etc before compiling, and then anything special afterwards?
Also will i need to get the nvidia patch for 2.6? |

Okay, this is what worked for me.
emerge development-sources and it'll grab the dependencies.
mkdir /sys
Make the /usr/src/linux symlink point to the 2.6 kernel.
Mount your boot and compile the kernel: make, make modules_install
cp the kernel image onto your /boot but call it something so you don't overwrite your existing kernel.
Create a new entry in your grub or lilo to boot up the new kernel. Grub doesn't need anything special.
Reboot into the new kernel and if you have a nvidia card, XDM/X will fail.
To get the nvidia card back up run:
emerge /usr/portage/media-video/nvidia-kernel/nvidia-kernel-1.0.4496-r1.ebuild
emerge /usr/portage/media-video/nvidia-glx/nvidia-glx-1.0.4496.ebuild
The latest 4496 Gentoo ebuild has the 2.6 patch in it.
Then insmod /lib/modules/2.6.0-test4/video/nvidia.o
You should now be able to get into X.
With ALSA I just compiled all my 2.6 kernel ALSA stuff as modules and it worked right on the initial boot. |

I guess I could've used this about a week ago. I decided not to do the 2.4 kernel and 2.6 kernel at the same time, it seemed to complicated at the time. One other tip, if you are going to install KDE and will use Konsole then you need to set these options in when configuring the kernel:
| Code: |
[*] Unix98 PTY support
[*] /dev/pts file system for Unix98 PTYs
|
If you don't then Konsole will open then close right away(as root) or will error upon opening then close(as a user). The Gentoo install instructions say that the second line listed above is not needed, well if you want Konsole you definitely need it if using the 2.6 Kernel. The first line I don't know for sure if you need it, I went with the 'better safe then sorry' theory and included it.
To respond to:

I don't have initrd in my grub.conf in either my midtower or laptop and they both boot fine. |

Something thats giving me a lot of grief at the moment is that the new generation module utilities ( with their new lower version numbers ) are causing build procedures that check the version of modutils ( i.e. pcmcia-cs, which I need ) to fail.
Bummer! I'm sure I'll come up with some hack for it though.

This turned out not to be a big issue. I used cardmgr compiled against 2.4 and card drivers out of 2.6. Pity the stock orinoco driver doesn't have rfmon support. :-/
The only remaining problem is the tty corruption on the neofb framebuffer driver. Will see if I can help the developer with it.

Hey swingarm,
The dev/pts filesystem has been depreciated.
What you need to enable is the /dev filesystem, and tell it to auto boot.
It built into 2.6 so it shouldn't be much of a problem.
Also fizz, initrd is used for autodetection under hotplug. If you custom compile your kernel you shouldn't need it.

this caused me some troubles too, as genkernel created this, but since this doesnt work yet with 2.6, i had to custom compile it & was left with a difficulty.
I Basically used the settings from the initial install docs, at the bit that covers the grub.conf file, those are the only bits you need (the lines that begin root & kernel, all others are for decoration). though if you use genkernel "bzImage" seems to be renamed "kernel-x.y.x"

If you just add another entry to grub.conf you should be able to boot your old kernel and the custom one quite easily.
Be careful though, I'm having massive problems with my nvidia-drivers and alsa.
